Episode Notes

When Sheldon describes one of his ideas for Amy's birthday present - an all-expense-paid trip to the "Wisconsin Sheep and Wool Festival" - Penny pauses and says, "Sorry, I was waiting for the Bazinga."

When Sheldon goes over to Penny's apartment to see her and Bernadette, they decide to have some fun with Sheldon's door knocking routine. When Sheldon knocks on Penny's apartment door, Bernadette tells Sheldon to come in, instead of Penny. This causes Sheldon to repeat his habitualistic known but calling for Bernadette. When Penny answers this time, Sheldon tells them to "Keep it up. I got nowhere else to be", at which point Bernadette tells Sheldon to just come in. Greeting the ladies, Sheldon tells them "For future reference, if I want to watch Mean Girls, I’ll stream it on Netflix."
